Abstract: 1,177,081. Apparatus for vacuum coating. BIR-VAC Ltd. Jan.18, 1967 [March 25, 1966], No.13448/66. Heading C7F. Vacuum coating apparatus comprises an electron emitting filament 38 mounted in an annular housing 34 an aperture 41 allowing the electron beam to bombard the source material in crucible 29 mounted on a turn-table 26 so that the crucible position can be displayed vertically in a continuously variable manner, and a conical shield 39 which shields a substrate 40 from direct heat radiation from the filament 38 see Figures 2 and 6. The assembly is mounted in a vacuum chamber and three shafts 7, 8, 9 with outside handle 10 extend through baseplate 1. Fixed to shaft 7 is sprocket wheel 11 connected by chain 12 to sprocket wheel 13 which on turning turns crucible 29 on turn-table 26 about a shaft 21. The shaft 8 is connected via running nut 15 to a pivoted lever 17 which is forked at 19 to engage collar 20 fixed to shaft 21 mounted so as to be rotatable and axially displaceable in plate 5. By turning handle 10 on shaft 8 the crucible 29 is thus displaced vertically. A shutter 33 is fixed to shaft 9 by arm 32 so that the shutter can swing into position above the filament 38 to prevent contamination of substrate (40) at the start of heating. It is swung away when vapour deposition is started. In operation the charged crucible is placed in one of the holes 27 while in position of Figure 3 (not shown). Shaft 7 is turned to bring the hole into the lower position shown in Figure 6, handle 10 is then turned to raise turn-table 26 into the upper position in Figure 6, this position being adjustable and dependent on the temperature required in the crucible. In a further embodiment shown in Figure 7 the crucible is shielded by housing portion 100 from heat radiation during electron bombardment and both the lifting and rotation of the crucible are produced by shaft 8. The end 106 of lever 17 cooperates with a ring of teeth 101 fixed to shaft 21 which has a bearing 102 connected to a ring of teeth 103. A lateral pin 104 fixed to shaft 21 cooperates with teeth 103 and spring 105 urges shaft 21 downwardly. Turning of shaft 8 lifts end 106 which rides up the flank of one of the teeth 101 and turns turn-table 26. A number of crucibles can be brought successively to the bombardment position for each reciprocation of end 106. Both conductive and non-conductive materials may be evaporated.

Abstract: 1507316 Optical memories E G N WESTERBERG 2 April 1975 [16 April 1974] 13526/75 Heading G4C In an optical memory employing a laser beam 4 to store information on a memory disc 1 the beam is modulated in intensity and deflected by an electro-acoustic cell 5 and an optical system 6, 10 between the cell 5 and the disc 1 is movable stepwise in the radial direction of the disc to provide coarse positioning of the beam. Each step of the coarse positioning device 11, 12 may shift the optical system by for instance the width of ten tracks on the disc; according to the frequency of an acoustic wave applied to the cell the beam is deflected to a greater or lesser extent; by choosing ten different frequencies at a generator 13 the beam may be positioned over any one of the tracks on the disc. In recording the data, that for one track of the disc is loaded into a 2<SP>14</SP> bit shift register 14 and then shifted out by synchronizing pulses read from the disc by an additional optical system 15, 16. The intensity of the beam is modulated by the data from the shift register so as to burn holes in the disc for 1 bits and leave opaque areas for 0 bits. For reading the memory the low intensity is maintained and the data is read, by a device 19, to the computer 29 via the shift register 14. A retroactive system may be employed to adjust the frequency of the generator 13 to locate the beam exactly in the middle of the track on the disc 1.

Abstract: 951,058. Automatic volume control. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 20, 1960 [April 23, 1959], No. 13838/60. Heading H4R. In an audio amplifier embodying automatic volume control, control voltages corresponding to at least two frequency bands are derived from the output signal and are then separately used to control the amplification of the frequency bands. A signal from the output of amplifier 3 is fed into a high-pass filter 5 so that when the voltage amplitude of a high-frequency signal exceeds the bias voltage 7, the anode current of valve 15 is reduced with a consequent decrease of emission from incandescent lamp 17 and hence increased impedance of photoresistor 20. Consequently low frequency signals are passed by low-pass filter 21, 20 with a decreased attenuation relative to that of the high frequency signals. A high voltage low frequency signal passed through low-pass filter 9 similarly increases the impedance of photoresistor 19 with a consequent increase of the low frequency impedance of the filter-capacitor 25, resistor 19. Amplifiers 2, 3 may also be gain controlled over an intermediate frequency band or over all frequencies by a voltage derived from the output signal by diode 22 and filter 23; the tappings on the resistors in filter 23 are for varying the bias voltages 7, 8 with respect to the output voltage.

Title: A method for producing globular fine particles of ª–-calcium carbonate
IPC: C01F11/18
Filed: 1966-03-29
Abstract: m -Calcium carbonate (vaterite) is produced from calcium chloride or nitrate and ammonium carbonate in an aqueous solution at 0-30 DEG  C. and pH between 8 and 12, stirring to produce CaCo3 gel and peptizing the gel by agitation to convert it to the crystalline m -CaCO3 form as globular fine particles which are immediately filtered, washed and dried at temperatures below 300 DEG C. for less than 2 hours. Saturated solutions are preferred.  The CaCl2 or CaNO3 may be formed in solution from a low grade Ca source (slaked or quick lime) with NH4Cl or (NH4)2NO3, recycling the filtrate to provide the NH4Cl or (NH4)2NO3 and adding CO2 to react with the liberated NH3 to form (NH4)2CO3. Peptization may be induced immediately after formation of the gel, or after standing for up to 30 minutes.  The possible standing time before autogenous peptization may be increased by dispersing agents such as a salt of lignin sulphonic acid, a sugar such as sucrose or mannitol, a polyhydric alcohol such as ethylene glycol or glycerine, an amine such as triethanolamine or an organic acid such as tartaric acid, citric acid or succinic acid in an amount, for example, between 0.01 and 0.1% by weight is added to the reacting solution.  According to examples, particles of average diameter 50 mm  to 2-3 m  were produced.  The fine particles are suitable for filling rubber or synthetic resins.

Drawings to Specification. Heading H2A. Coil omission in symmetrical pole-amplitude modulation is avoided by the mutual bucking of adjacent coils. Pole-changing by symmetrical pole-amplitude applies where neither polenumber is three pole-pairs or a multiple thereof, and the omission of certain coils in the modulated connection is described in the parent Specification using integral slot machines for the purpose of reducing the amplitudes of the poles at the ends of the modulation waves to provide a near-sinusoidal modulation wave. According to this invention, the omission of coils is avoided by energizing certain adjacent coils in bucking relationship to all the remaining coils of the coil-group providing the said poles of reduced amplitude, so that, although they are still connected in circuit, no net effect is produced by the two adjacent bucking coils. In the example given, an 8-pole machine having three slots per pole per phase is modulated to give 10-poles as described in the parent Specification by reversal of half of each phase together with the reduction of end-poles of both half-waves by coil-omission. The modulated phase-bands are then:- where the omitted coils are indicated as " 0." According to the present invention, the same effect is produced as follows:- Detailed layouts are given in which, for instance, the reversal of coil 1 of phase A is equivalent to the omission of coils 1 and 2 (Fig. 1, not shown).
